Astelin
® (
azelastine hydrochloride) is a prescription medication approved to treat sneezing, runny or stuffy nose, and nasal itching (known medically as rhinitis). The medication is approved to treat these symptoms when they are due to either seasonal allergens (known as seasonal allergic rhinitis) or to other irritants (known as rhinitis or vasomotor rhinitis).
Astelin is made by MedPointe Pharmaceuticals.
Allergies occur when the body's immune system reacts to a normally harmless substance -- one that does not bother most people. This reaction is partly caused by the release of histamine from certain cells, known as mast cells. Astelin is an antihistamine nasal spray that acts in at least two different ways. It helps prevent the release of histamine from mast cells, and if any histamine is released, Astelin prevents it from binding to histamine receptors. Since histamine is responsible for many of the symptoms of allergies, blocking it can be helpful.
It is not known exactly how or why Astelin works for vasomotor rhinitis. Traditionally, it was thought that antihistamines were generally ineffective for this condition, since vasomotor rhinitis does not involve an allergic reaction or immune system response. However, studies have shown that Astelin nasal spray helps with vasomotor rhinitis.
Astelin has been evaluated in studies for treating nasal
allergies. In these studies, the drug helped to decrease the following symptoms:
- Sneezing
- Runny nose
- Itchy nose
- Watery eyes
- The need to blow the nose.
Studies have shown that Astelin begins working within 3 hours and lasts at least 12 hours. Studies have also shown that Astelin is effective for treating vasomotor rhinitis (nasal symptoms caused by irritants, not allergies). The medication decreased the following symptoms:
- Runny nose
- Nasal congestion
- Sneezing
- Postnasal drip (nasal mucus dripping down the back of the throat).
When and How to Take Astelin
General considerations for when and how to take Astelin include the following:
- Astelin comes in the form of a nasal spray. It is usually taken twice a day.
- The first time you use each bottle of Astelin, you will need to prime the pump by spraying until a fine mist appears. If you have not used the bottle within the last three days, you may have to re-prime the pump.
- Blow your nose before each dose. Breathe in gently while spraying the medicine into your nose. Do not try to inhale the spray or breathe in too deeply, as Astelin works when it comes into contact with the inside surfaces of the nose, not the throat or lungs.
- Do not tip your head back immediately after taking Astelin, as this increases the chance of experiencing a bitter taste.
- For the medication to work properly, it must be taken as prescribed. Astelin will not work if you stop taking it.
Dosing Information for Astelin
The dose of Astelin that your healthcare provider recommends will vary, depending on a number of factors, including:
- Your age
- Whether your nasal symptoms are caused by allergies or irritants
- Other medications you may be taking
- Other medical conditions you may have.
As is always the case, do not adjust your Astelin dose unless your healthcare provider specifically instructs you to do so.
As with any medicine, side effects are possible with Astelin. However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.

- Bitter taste
